Fishes of the family Myctophidae, commonly known as lanternfishes or myctophids, are a group of fishes with over 400 species. They are part of a large, underutilized biomass of mesopelagic fish species. Myctophids reserves in the world's oceans have been estimated at 550- 600 million tons. The largest lanternfishes reserves exist in the Arabian Sea and the Southern Ocean. Only a few myctophids species being edible (<10 species). They are a good source of proteins, amino acids, lipids, fatty acids, and minerals, which can be utilized in different industries. This review reports the prototypes and products made from myctophids and their properties based on published documents. Furthermore, distribution, biomass estimation, and fishing of myctophids and post-harvest changes and physicochemical properties of myctophids flesh are underlined. Challenges for further development of the myctophids industry and quality management of handling and processing of this resource are also addressed.

Mesopelagic Species

Abstract During three cruises in the Mid Atlantic Ridge area in 2016 and 2017, we studied the biomass of mesopelagic fish and its potential as a source of protein and oil for animal feed and human consumption. We collected samples of mesopelagic species down to a depth of 600 m, studied fish behaviour, identified and quantified the species composition of the catches, analysed the chemical composition of the catch samples, and evaluated the presence of unwanted substances. Results showed that Maurolicus muelleri (Mueller’s pearlside) and Benthosema glaciale (Glacier lantern fish) were the most abundant fish species in our samples and catches containing 80% fish can be a good source of protein and marine lipids including eicosapentaenoic acid (C20:5n3) and docosahexaenoic acid (C22:6n3). Unwanted substances, except for Cd and As, were present at levels far lower than the limits set by European Union regulations. However, our experiments identified challenges that may limit the efficiency of commercial operations in the Northeast Atlantic. Combined real-time optical and/or multifrequency acoustic systems will be needed to improve species identification and ensure cost-effective fishing operations. Also, selective trawls that target only fish and release unwanted species are needed to secure high-quality oils and proteins.

This article deals with the results of study of species content and basic peculiarities of beaked mites-Phytoseiidae in plant associations of one of the regional centers of Ukraine. The species composition and distribution of mites-Phytoseiidae (Parasitiformes, Phytoseiidae) in plantations of Brovary town of Kyiv region were determined. Fourteen species of 8 genera of phytoseiid mites were found. Index of their existing and relative biotope connection of each registered species to vegetation types and plant species were computed. The study was conducted according to the results of material treatment on the territory of the mentioned city from 25 species of plants (16 species of hardy-shrub and 9 of herbaceous vegetations). The studies of distribution of plant-living mites-Phytoseiidae were conducted separately for hardy-shrub and herbaceous plants). The collection of faunistic material was executed during the vegetation of periods of 2011 and 2013. Within the city the collection of the material was conducted with hardy-shrub plants and herbaceous type of vegetation along the streets, in parks and squares of Brovary city of Kyiv region, district center, one of the satellite-cities of Kiev, the capital of Ukraine. The study of species complexes characteristics of mites was conducted with usage of data calculated on the basis of frequency index (Is), degree of relative habitat confinedness (F) (Pesenko, 1982) and domination index Paliy-Kovnatski (Di) (Shitikov, 2003). Only on one species of plant (F=1) 6 species of mites-Phytoseiidae were found – T.сotoneastri on blue spruce, T. laurae – on common spruce, T. aceri – on ash-leaved maple, P. incognitus – on dog-rose, P. soleiger – on mulberry-tree, A. caudiglans – on sea-buckthorn. These species can be related to stenoecic. The mentioned species are stenotopic only in relation to the sample of plants from the plant associations of Brovary, as in other regions these species of mites can populate the other species of plants. The rest 8 species, being registered on two or more types of plants, are related to euryoecic. Among them there is a group of 6 species with “positive tendencies to population of plants”, owning the indicators of habitat confinedness 0<F<1: A. andersoni (0,92–0,96), A. rademacheri (0,85–0,96), N. herbarius (0,92–0,96), T. tiliarum (0,66–0,77), A. pirianykae (0,73–0,99), A. clavata (0,82–0,98). The rest species, E. finlandicus и K. aberrans, have the expanded range of indicators in relation to habitat confinedness (-0,71<F<0,55 и -0,16<F<0,88), that specifies on their ability to populate the big quality of species. E. finlandicus has the negative indicator of relative habitat confinedness in relation to the plants of herbaceous morphotype that serves confirmation of the ecological peculiarity of the species detected earlier. The data of relative habitat confinedness of mites to certain species of plants shows availability of stenoecic (T.сotoneastri, T. laurae, T. aceri, P. incognitus, P. soleiger, A. caudiglans) and euryoecic species (A. andersoni, A. rademacheri, N. herbarius, E. finlandicus, K. aberrans, T. tiliarum, A. pirianykae, A. clavata).

A comprehensive review is carried out on the models and correlations for solid/fluid reactions that result from a complex multi-scale physicochemical process. A simulation of this process with CFD requires various complicated submodels and significant computational time, which often makes it undesirable and impractical in many industrial activities requiring a quick solution within a limited time frame, such as new product/process design, feasibility studies, and the evaluation or optimization of the existing processes, etc. In these circumstances, the existing models and correlations developed in the last few decades are of significant relevance and become a useful simulation tool. However, despite the increasing research interests in this area in the last thirty years, there is no comprehensive review available. This paper is thus motivated to review the models developed so far, as well as provide the selection guidance for model and correlations for the specific application to help engineers and researchers choose the most appropriate model for feasible solutions. Therefore, this review is also of practical relevance to professionals who need to perform engineering design or simulation work. The areas needing further development in solid–fluid reaction modelling are also identified and discussed.

Cranberry stem gall is characterized by tumors that girdle stems, thereby killing all distal leaves, flowers, and fruit. Among bacteria isolated from galls, all 11 isolates that were identified as members of the family Enterobacteriaceae caused galls on 50 to 100% of micropropagated cranberry plants that were inoculated. Four of fifteen isolates identified as Pseudomonas spp. caused galls on 10 to 83% of plants inoculated. Twelve of fifteen isolates identified as either Agrobacterium spp. or Rhizobium spp. caused galls on 10 to 50% of plants inoculated, but the galls were smaller than those caused by members of the family Enterobacteriaceae or Pseudomonas spp. There was a positive correlation between the ability of bacteria to produce IAA in vitro and cause galls. In 2002 and 2003, bacteria were isolated from plant and soil samples collected from beds where stem gall had been observed in the past 2 years and beds where stem gall had never been observed. IAA-producing bacteria were common in all samples, although trends were different across years. The results of this study support the hypothesis that IAA-producing bacteria cause cranberry stem gall and suggest that rather than one bacterial species being the cause, multiple strains of bacteria that produce IAA may be responsible for gall formation.

Tegalharjo village is a village in Glenmore sub-district, Banyuwangi district, which has a very large plantation area with a variety of plants. One of the plants that thrives on plantations and people's homes is the cassava tree. But the use of cassava as a village's potential to improve the economy of citizens is less than optimal. Cassava is generally left to rot in the trees, sometimes sold cheaply with a maximum price of Rp 3.000.00 a kilo gram and even ironically it is only used as animal feed. Meanwhile the majority of housewives only depend on the family economy for their husbands' work as farmers, farm laborers, very few who are self-employed and plantation labour majority. Seeing this, there needs to be innovations that can increase the economic value of cassava. One of them by processing cassava into brownies. After being processed into brownies, the selling value automatically increases from a kilo of Rp 3.000,00 to Rp 10,000.00 in a package. This innovation was carried out by the service team through mentoring activities and training in making Brownies of Cassava.

Pain Experiences

The family has long been acknowledged as an important social context where children learn about and receive support for their pain. When a child is in pain, it is the family who is responsible for the initial pain assessment and seeking appropriate evaluation and care. Families may inadvertently encourage the expression of pain and play a critical role in influencing their children’s ability to cope with pain, both positively and negatively. Having a child in pain can also pose significant personal, familial, and economic strains. Therefore, consideration of the family is absolutely critical in the understanding of factors involved in children’s acute and chronic pain experiences (McGrath, 2008). A concentration of research has continued since the last comprehensive review on the topic was published (Chambers, 2003). This chapter considers relevant theoretical models and summarizes current major research themes regarding the role of the family in both acute and chronic paediatric pain. Two illustrative case examples are provided and key areas for future research are identified.

Purple sweet potato anthocyanins are kinds of natural anthocyanin red pigments extracted from the root or stem of purple sweet potato. They are stable and have the functions of anti-oxidation, anti-mutation, anti-tumor, liver protection, hypoglycemia, and anti-inflammation, which confer them a good application prospect. Nevertheless, there is not a comprehensive review of purple sweet potato anthocyanins so far. The extraction, structural characterization, stability, functional activity, application in the food, cosmetics, medicine, and other industries of anthocyanins from purple sweet potato, together with their biotransformation in vitro or by gut microorganism are reviewed in this paper, which provides a reference for further development and utilization of anthocyanins.
